NBA owners are holding players’ feet to the fire, insisting on a more favorable labor deal, since, as they claim, the league as a whole lost over $300 million last season and 23 of the 30 teams are losing money. That may or may not be true, but what seems undeniable is that NBA owners are extremely wealthy.

In fact, according to a Forbes report cited by I am a GM, 12 NBA owners rank among the 400 richest people in America. Nuggets owner Stan Kroenke, however, is the only person on the list for whom “sports” is listed as the primary source of wealth.

Here’s where NBA owners rank on the list, as well as reported net worth.

No. 60 Richard DeVos, Orlando Magic, $5 billion

No. 75 Mickey Arison, Miami Heat, $4.2 billion

No. 107 Stan Kroenke, Denver Nuggets, $3.2 billion
